PIPE-CASE.

Specification of Letters Patent.

Patented July 23, 1912.

Application filed April 26, 1912. Serial N 0. 693,354.

To all whom it may concern:

Be it known that I, JOHN N. WHITE- HOUSE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pipe-Cases, of which the following is a specification.

My present invention relates to a celluloid pipe case wherein the mouths of the two halves of the case are provided with flanges of a special construction which snap one within the other to secure the halves of the case in closed position in a neat, compact and effective manner.

The nature of my improvement willbe readily understood from the following clescription in connection with the drawings.

In these, Figure 1 shows a side elevation of one form of pipe case within my invention, the case shown being adapted to contain a curved bit pipe; Fig. 2 is an underneath plan view of the pipe case of Fig. 1; Fig. 3 is a vertical section on the line 3-3 in Fig. 1 looking in the direction of the arrows, showing the two halves of the case closed on each other; Fig. 4 is a similar view except that the two halves are shown partially open as if in the act of being closed; and Fig. 5 is a detail cross sectional view on an enlarged scale of the flanged portions of the respective halves of the case to illustrate the principle of construction.

I will now describe the specific devices of the drawings.

The pipe case is intended to be made of celluloid or equivalent material, and is molded therefrom in two longitudinal halves 1-1 which are hinged together at 22. The mouth of each half has a narrow trough-like flange (see Fig. 5) around it designated 3 and 4 for the respective halves. The trough-like flange 3 is conveniently called the inside flange because it fits inside the other or outside flange 4 when the halves of the case are closed on each other. For this purpose, the outside face of the in side flange 3 fits or conforms to the inner face of the outside flange 4- Referring again to Fig. 5, the dotted corners show the portions which may be regarded as having been removed during manufacture to produce the flanges of the finished article shown in the preceding figures. Thus, the inside corner 3 in Fig. '5 of the inside flange is beveled off, as is also the outside corner 4 of the outside flange. The result of this beveling is that the edge thickness of each flange is reduced so that they cannot abut against each other edge on to interfere with the closing of the case; and this is accomplished without interfer ing with the previously described snug locksurface of the outside flange 4L wit-h the outer surface of the inside flange 3. Fig. 4 shows how one beveled edge rides up on the other in closing the halves of the case, and Fig. 3 shows how the two trough-like flanges finally interlock to hold the halves of the case in closed relation.

5 is an external projection or finger at the base of the inside flange 3 which acts both as an abutment for the beveled edge of the outer flange 4 to prevent the halves of the case from being telescoped too far on each other, and further acts as a finger-piece against which to press in opening the case.

Of course, it will be understood that the case will ordinarily be made by molding the celluloid and not, for instance, by actually beveling, by a cutting or filing instrument, the referred to corners 8 and 4 lVhat I claim is:

A celluloid pipe case in two longitudinal halves hinged together, the mouth of each half having a narrow trough-like flange around it, the inside of one of said troughlike flanges fitting or snapping over the outside of the other flange when the two halves of the case are closed on each other, the inside corner of the inside flange and the outside corner of the outside flange being respectively beveled off.

In testimony whereofI affix my signature in presence of two witnesses.
